No, it's very capitalistic: IP is capital on which rent can be charged, so naturally the system coerces transfer of ownership to the rentier class and away from the labour class. :(
One of the main improvements of capitalism over feudalism is that contract terms usually last for at most a lifetime, and where they don't they're at least limited to a piece of real estate.
That's quite wrong. the very basis of IP is a state-imposed monopoly, which is the complete opposite of what capitalism is, what its basic principles are, and how it works.
That's not to say there aren't some good arguments for IP, but they sort of inherently have a planned-economy bent.
